Advanced composite analysis

Element deletion
New

Helius PFA works with Abaqus Standard and Explicit to remove elements from a simulation due to various failure modes. You can improve convergence, efficiency and accuracy by running these realistic simulations.

Reduced mesh sensitivity

Use energy-based damage evolution to control the rate of material degradation for your composite structure. The rate of stiffness degradation typically decreases as the size of the element decreases. Specify the finite energy dissipation from failure of the fibre and matrix constituents to reduce the mesh sensitivity.
